Abstract
The utility model discloses a cooling device for a shaft furnace. The cooling device comprises an air inlet (1), an air outlet (2) and a waste gas purifying device (3), wherein the air outlet (2) is arranged on the lower part of the air inlet (1); and the waste gas purifying device (3) is connected with the air outlet (2). The cooling device has the advantages of excellent cooling effect of pellet ore, low discharge temperature, prolonged service life of discharge equipment such as a toothed roller discharging machine, and the like, higher operation rate and increased output of the shaft furnace; meanwhile, a great amount of sensible heat carried off by original pellet ore is recycled, thereby realizing energy conservation and consumption reduction.
Description
Technical field
The utility model relates to a kind of shaft furnace, relates in particular to a kind of shaft furnace cooling device that has the interior secondary cooling air of stove and be used as combustion air after purifying.
Background technology
Shaft furnace of the prior art, for once cooling air provides hot waste gas for the soaking zone provides oxygen and oven dry bed simultaneously as the cooling ball nodulizing.Its existence be that cooling air quantity is not enough than distinct issues, pellet fails effectively to be cooled off, directly " red ball " discharges, and shortens ore discharge service life of equipments such as spike roll discharger, influences the shaft furnace operating rate; Pellet is taken away a large amount of sensible heats again simultaneously, is unfavorable for energy-saving and emission-reduction.
Summary of the invention
The purpose of this utility model provides a kind of shaft furnace cooling device that reclaims its sensible heat in shaft furnace in the cooling ball nodulizing with regard to being at above-mentioned prior art present situation.
The technical solution of the utility model is: a kind of shaft furnace cooling device comprises the cooling device of air inlet (1), exhaust outlet (2) and waste gas purification apparatus (3).
Further, the air inlet (1) of described air inlet (1) and existing shaft furnace same position.
Further, described exhaust outlet (2) can also can be on top in the bottom of air inlet (1).
Further, described waste gas purification apparatus (3) links to each other with exhaust outlet (2), is used to purify hot waste gas.Hot waste gas after the purification is introduced combustion chamber (5) as combustion air.
Adopt the technical solution of the utility model, owing to increased the air quantity of cooling air, the pellet cooling effect improves, and reduces its ore discharge temperature, prolongs ore discharge service life of equipments such as spike roll discharger, improves operating rate, increases shaft furnace output; Reclaimed simultaneously a large amount of sensible heats that former pellet is taken away again, energy-saving and cost-reducing.
Description of drawings
Fig. 1 is the schematic diagram of the utility model first embodiment shaft furnace cooling device.
Fig. 2 is the schematic diagram of the utility model second embodiment shaft furnace cooling device.
The specific embodiment
Embodiment further describes the utility model below in conjunction with accompanying drawing.
First embodiment, air by cooling blower (4), air blast enter shaft furnace air inlet (1), portion of air makes progress away, the cooling ball nodulizing provides hot waste gas for the soaking zone provides oxygen and oven dry bed simultaneously, is a cooling air; Another part air is walked downwards, further cools off pelletizing, is the secondary cooling air, and, enter hot waste gas purifier (3), the hot waste gas after the purification from exhaust outlet (2) discharge, introducing combustion chamber (5) utilizes once more makes combustion air, has reclaimed a large amount of sensible heats that former pellet is taken away, energy-saving and cost-reducing.
Second embodiment, air by cooling blower (4), air blast enter shaft furnace air inlet (1), air makes progress away, a part of cooling ball nodulizing provides hot waste gas for the soaking zone provides oxygen and oven dry bed simultaneously, is a cooling air; Another part air is discharged in advance, is the secondary cooling air, after discharging from exhaust outlet (2), enter hot waste gas purifier (3), the hot waste gas after the purification, introducing combustion chamber (5) utilizes once more makes combustion air, reclaimed a large amount of sensible heats that former pellet is taken away, energy-saving and cost-reducing.
It should be noted that at last: above embodiment only be used to the utility model is described and and the described technical scheme of unrestricted the utility model, the utility model can also have multiple improvement and other preferred embodiment, therefore, although this specification has been described in detail the utility model with reference to the above embodiments, but, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the middle of the claim scope of the present utility model.
Claims (3)
1. shaft furnace cooling device is characterized in that comprising the cooling device of air inlet (1), exhaust outlet (2) and waste gas purification apparatus (3), and described exhaust outlet (2) is in the bottom of air inlet (1).
2. shaft furnace cooling device as claimed in claim 1 is characterized in that described exhaust outlet (2) also can be on the top of air inlet (1).
